THERAPEUTIC LIGHT APPARATUS.

Application filed August 1, 1927. Serial No. 209,890.

The main objects of this invention are:

First, to provide an improved therapeutic lamp which is portable and well adapted for use in hospitals, sanitariums and the like and to be adjusted at the side of a bed or cot for treatment of a patient lying thereon.

Second, to providean improved therapeutic lamp apparatus which has a considerable range of adjustment, which adjustment can be readily efl'ected.

Third, to provide an improved therapeutic lamp apparatus employing a series of arc lamps in which the lamps have a common control means.

-Fourth, to provide an apparatus having these advantages which is not likely to get out of repair.

@bjects pertaining to details and econornies of my invention will definitely appear from the description to follow. The invention is defined in the claims.-

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing in which:

Fig. 1 is a front elevation of my improved therapeutic lamp structure.

Fig. 2 is an end elevation looking from the left of Fig. 1.

Fig. 3 is a vertical section on line corresponding to line 3-3 of Fig. 2, parts being broken away for convenience in illustration.

Fig. 4 is a detail section on line 44 of Figs. 1 and 5 showing details of the adjusting means.

Fig. 5 is a detail section on line 55 of Fig. 4: showing further details.

Referring to the drawing, the embodiment of my invention illustrated comprises tubular standards 1 having cross pieces 2 at their lower ends. Downwardly diverging braces 3 extend from about midway of the standards to the ends of the cross pieces 2. These braces have vertical bottom portions 4 below the cross pieces 2 carrying the caster wheels 5. The standards are connected by longitudinal bars 6, the top bars being substan tially spaced from the upper ends of the standards.

Uprights 7 telescope within the standards and are secured in their adjusted positions by the thumb screws 8. Collars 9 are mountcurrently herewith.

ed on the upper ends of the standards as finish members and also to receive the set screws.

I provide a reflector 10 which is elongated and comprised of a cylindrically curved segment. The reflector is supported by the longitudinally projecting spindle-like arms 11 which are secured on the outer side of the reflector by means of the clips 12, the arms being disposed adjacent one edge of the reflector. These arms are adjustably mounted on the uprights 7 by means of the split clamping collars 13. The collars have pro ecting lugs 14 at one side to receive the clamping screws 15.

On the arms 11 are stop-arms 16 carrying the spaced stops 1? coacting with the uprights 7 to limit the swing of the reflector so that when the clamps are released the reflector will not swing too far in either direction, and prevents the same getting out of control while being manipulated.

In the structure illustrated ll provide a pair of lamps, the bottom electrodes 18 being supported in holders 19 carried by the rods 20 and 21 depending within the reflector. The top electrodes 22 are provided with holders 23 carried by the clutch rods 24 projecting through the wall of the reflector. The feed clutches 25 are connected by the links 26 to arms 27 on the rockshaft 28 which is supported in hangers 29. The rockshaft 28 is o eratively connected to the armature 30 of tlie solenoid 31, a common control thus being provided for the lamps.

The amps are connected in series as described in detail in my application for Letters Patent on are lamp apparatus filed con- As these features are made the subject matter of such application, they are not described with further detail herein, it being believed that it si suflicient here to point out that the lamps are connected in series and have a common feed or control means.

As these lamps are to be used for the administering of light treatments, it is desired to provide the carbons or electrodes with screens which comprise the holders 31 provided with upwardly projectin arms 32 terminating in fingers 33 detachab y enga cable with the collars 34: on the electrode older be readily supports 20 and 21. These arms 32 have spring clips 35 below the fingers to engage the rods 20 and 21.

With this arran ement the screens can remove when it is desired to ad'ust the lower carbons or clean the screens.

lWy improved therapeutic lamp apparatus may be moved about as from cot to cot in a ward, or from room to room, is very simple in structure and not likely to get out of repair, there being comparatively few parts.

The lamps being connected in series and havin a common control, they are kept uniform y adjusted; that is, the carbons are ad'usted so that one cannot rob another.

l have illustrated two lamps but it will be understood that more may be employed if desired.

I have not attempted to illustrate certain other adaptations and certain modifications which I contemplate as I believe this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
